If you're down for the saving the environment, show off your fashionable do-gooder side with Teresa Missoni's cool tee. Margherita's little sister, along with Angela Lindvall and Irina Lazareanu, are part of LENY's (Limited Edition New York) campaign to save the climate. T-shirts, retailing for a whopping $180, will be available next month. Pretty pricey but it's for a good cause. Proceeds from the tees — all designed for free — will benefit Al Gore's Climate Project.
